Refund Policy

Updated: [date, replace] · Effective: [date, replace]

1. 7-Day No-Questions Refund

Within 7 days of payment, you may request a no-questions refund. If you have not actually used the core diagnosis features, we will refund the full amount of this payment.

2. Used Services

• If you have already used core features such as diagnosis or report export within 7 days, you may still request a refund; we will deduct a reasonable fee for the used portion and refund the difference, or discuss alternatives with support.
• Test licenses redeemed with "friend test codes" are not refundable.

3. Non-Refundable Cases

• Normal expiry or renewal requests beyond the 7-day window;
• Feature limitations caused by expired or low-balance user-provided API keys or unavailable third-party AI services;
• Suspension or termination due to breach of the Terms of Service.

4. How to Request a Refund

1. Email support@schemasandbox.com (replace) with "Refund Request" in the subject line;
2. Include: order number or payment receipt, customer name, and the reason;
3. We review and reply within 5 business days; approved refunds are returned to your original payment method (typically 3–15 business days depending on the payment channel).

5. Refund & License

Once a refund is confirmed, the corresponding software license is revoked and becomes invalid; please stop using it. Revocation does not affect your on-device history.

6. Disputes

If you disagree with a refund decision, contact support; if unresolved, disputes are settled under Section 12 of the Terms of Service.
